ATTORNEYS,

Patented Apr. 26, 1938 UNITED ISTATES DECORATIVE I-.AMINATED ARTICLE AND METHOD 0F MAKING THE SAME George M. Soule, Cleveland, Ohio, assign'or to Oxford Varnish Corporation, Detroit, Mich., a corporation of Michigan Application February 5, 1936, Serial No. 62,493

` 'z claims. (c1. n n) This invention relates to a substantially rigid decorative'article having a transparent display sheet, such as glass on one side, and to a novel process of producing such article.

A further object is to provide a rigid decorative unit of the kind above mentioned and particularly one that will not be subject to destructive change under the chemical action of moisture, air and gases normally contained thereby and which will notv be subject to destructive change by the action of light.

Another object is to provide a decorative unit, including a glass face member, which unit will be highly resistant to variations intemperature.

A specific object is to provide an improved decorative `glass sandwich and novel process of producing the same, particularly one adapted for decoration in representation of natural or articial patterns, such as wood, marble, tile, animal skins, textile appearances, etc.

TheA invention is o ne the order of that disclosed by the copending application of Lloyd V. Casto, Serial No. 45,927, iiled October 21st, 1935, owned by the assignee hereof, and is characterized particularly in that the .decorative treatment is es pecially adapted to be subjected to a iiring or sintering operation, suiiicient to substantially homogeneously unite part or all of the decorative treatment with the glass, to the end that the decorative treatment will remain substantially without change throughout the life o'f the glass, and will not be subject to pulling away from the glass and/or other destructive changes, commonly experienced in connection with so-called non-splintering glass.

The invention contemplates the utilization, in a decorative glass sandwiclnof vitreous or nonvitreous enamels and/or .color materials, applied to the glass, as will be hereinafter described, and subject to treatment to sinter or fuse the same to render them chemically inert or substantially so under ordinary conditions of use.

Exemplary embodiments of the invention are shown in the accompanying drawing, Figs. 1 to 3 of which each represents an enlarged cross-secv tional view of a section of acompleted composite Y the material 4 in operative effect, the entire companel.

While all these figures show a two-way view panel, that Ais, reversible so that either side may be exhibited to advantage, the invention is in no way limited to this arrangement since, in general, it may be practiced substantially without change in producing single-face-display panels.

' Referring to Fig. 1, sections of two glass ysheets vare shown at I and 2, an open design transfer is as in a furnace or oven.

Alight diii'using, or enhancing the bond, or vsubsenting lithic materials such as stone or marble indicated at 3, and a bonding and/or ground color intermediate body layer is shown at 4.

The transfer 3 preferably comprises the class of material embracing vitreous and non-vitreous enamels adapted to be red or sinte'red ont'o 5 the surface of the glass by the application of heat,

The surface of the glass on which the transfer is applied may be rough (as frosted) say for 10 stantially smooth as with ordinary plate and window glass, and this selective variation applies to all forms. A frosted or granular appearance or surface may be used to advantage in repre- 15 and likewise in representing certain types of Wood, the ground appearance'of which appears on close observation to be granular.

component to serve as a background for the trac- 20 ery effect at 3. This body may be of vitreous material vor plastic or semi-plastic material, depending somewhat upon the contemplated use or environment of the completed article. For ex ample, the body 4 may comprise a material such as an asphalt base paint, with the admixture. of proper coloring matter, etc. when necessary, to. produce-the desired background effect. In this form the body 4 acts as a cushion between the two glass sheets I and 2, and also as an 'effective sealing agent throughout the entire laminated surfaces and at the edges. If a comparatively thick layer of such plastic material is employed, this will, at all marginal edges, become substantially hard, but will remain plastic over the intermediate areas.- v

Alternatively, the body 4 may comprise ceramic materials, the laminating being done as by coating one or both of the decorated panels (in case of a two-way view sandwich) with the raw (plastic) color e. g. material and the panels then brought together and the whole assemblage then Asubjected'to the proper degree of heat to fuse or sinter the body 4 and/or the decorative treatment 3. If the body 4 is of'vitreous or non-vitreous enamel and the design transfer 3 is similar to It is to be understood that the body 4, may be 55 translucent or transparent or opaque; and may Vflake or powder in natural state. Moreover,

either may contain an insuii'icient amount of pigment or color material to prevent the viewing of both design transfers 3 through a single sheet, such as above described, this being of' distinct advantage Where a different design is applied to each glass sheet, such arrangement giving depth .and changeability of appearance to the panel when viewed from various angles. The design treatments 3 in such event are preferably different l may be done in accordance with the patent to designs or if the same then definitely offset from each other, as by reversal of position, to avoid near' registration -or dizzy effects.

It should be mentioned that the open design transfer 3 may be applied in the manner of applying graining paste in wood and other natural pattern graining methods. For instance, this J. P. Henry, No. 1,548,465, issued August 4th, 1925, or for further illustration according to the patent to R. F. Brown, No. 1,685,396, issued Sep`tember'25th, 1928. Other suitable definite transfer processes, such, for example, as offset lithography and decalcomania, (as in china decoration), may also be used. For the open design treatment the surface of the glass maybe etched through al suitable resist and the color applied over the entire surface but being retained only in the etched area. Lusterization and iridescent eects, when and if desired, are 0btained as in china and glass decoration, various methods being well known. y

' Referring to Fig. 2, this illustrates the decorative'design transfers 3, over which there is applied (on each one, for example) vitreous or nonvitreous enamel material 5, fired or sintered on as determined by the material used, the two Sections so built up as rigid units being united either by fusing or sintering the two bodies 5 together (or by fusing or sintering one body to a glass sheet, in case of a one-way view sandwich) or by the interposition of a separate bonding layer of material, such as I5 between the two layers 5. The layer B'may be plasticor rigid, (as above described, in respect to the layer 4), inA the nnished article. The layers 5 may contain the proper ground color or component or both layers 5 maybe transparent or highly translucent andi the effective or predominant ground color fur-Y nished by the layer 6, by theuse of appropriate pigment or Adye contained therein.

l Fig. 3 illustrates an arrangement similar to that of Fig. 2, and in addition, specifically, the employment of a rough, crystalline or granular surface at 1, on the underside of the coating such as 5', which is laid over the designrtransfer on the glass. This may be the same on each panel as indicated, and the roughening treatment may comprise frosting, (etching e. gr.) sand-blasting or the like, or the'well-known wrinkled finish may be effected in applying each or either layer 5. In the event the coating 5' is substantially transparent or highly translucent, such wrinkled nish imparts a granular 'or crystalline effect to the vground and/or design color, it being understood that the design transferA 3 may also be pervious to reilected light to any desired degree.

As indicated above, the selection of decorative materials for the various described imprints and.

others. However, in order that the use of the .Y

invention will not be confined to specially selected glass, I, propose, generally, to use colored enamels containing active uxes, such as borates of lime and lead, ground and suspended in suitable vehicles, such as varnish or drying oil for application to the glass or over a. previous decorative imprint or transfer thereon.

For the reproduction of oak, as a specific example, one uses for the designs imprints 3, brown or black producing colors such as ferrie oxide with zinc, nickel or cobalt oxides as toning agents, in case of a brown; or cobalt oxide with ferric oxide, manganese oxide etc., in case blacks and near blacks are desired. Then as a suitable ground color 4, 5 or 5', e. g. this being generally yellow is obtainable by using barium chromate,

lead chromate, uranium compounds etc., with or Without toning shades depending on the color of f the wood e. g., sample to be copied or simulated. The fluxes for said colors are variously prepared,

as well known in the ceramic arts. Examples may be found in the text Glass Technology (Hodkin and Cousen) 1935 edition page 413.

The fusing or sintering treatment is carried out as usual in a suitable kiln at appropriate heats and, particularly when the color materials are to be reduced to true glazes, the glass sheet or sheets are re-annealed on cooling down the kiln.

I claimz- I. 'I'he process of producmg a decorative glass sandwich comprising applying to one face of a glass panel a decorative treatment of translucent ceramic color material, fixing or sintering said material, and roughening the back of the fired material to impart thereto, when viewed through the opposite face of the panel, a granular appearance.

2. In a laminated decorative article of the class described, a glass panel, a decorative coating on the back of the panel igneously' bonded therewith and at least-partially translucent, the back of the coating being granular for diffusing light reflected through the translucent portion thereof and through the panel.

3. In a laminated article of the class described,

two glass panels, an open design transfer and ground color coating on each, igneously bonded to the respective glass surfaces and a laminating bonding sheet attaching' said panels together.

4. In a decorative glass sandwich, two glass y panels, an open design in color material and a translucent layer on each, said layers having appearances contrasting with the respective designs and igneously bonded with the respective glass surfaces, and an intermediate-bonding layerhaving a color perceptible through the respective translucent layers and panels.v a

5. The process comprising 'applying an open design tracery ln color material of the .ceramic type onv one side of a display glass panel, lgneously bonding the material thereto and igneously bond-- ing a rigid body layer having a color contrasting with said tracery to said panel for visibility thereof through the display glass panel. y

6. The process comprising-applying an open design comprising sinterable or fusible color material to one face of a glass panel, applying a sinterable or fusible ground color coating over the design, subjecting the' whole to a temperature suiciently high to sinter or'fuse the color material and unite the same with each other and fuse them to said paneLand attaching another glass panel to the decorative treatment and causing said panel to adhere with less force than does the ldecorative treatment to the first glass panel.

'7. The process of producing a. decorative sandwich, including a glass facing, comprising applying decorative treatment including an open design and contrasting background, one lapplication comprising sinterable or fusible color material, to one surface of a substantially transparent display glass panel, subjecting said material to sintering or fusing heat, attaching a rigid backing panel to` the back of the decorative treatment, and causing the latter panel to adhere thereto with less force than does the sinterable or fusible color material to the display glass panel.
